Issues installing on ubuntu 18.04

I ran into some issues installing on my laptop (ubuntu 18.04). This details the workarounds I went through:

I installed kivy using the PPA. Installed pyserial via apt. When I launched it, I got the following error:

Kivy mentioned that it was dropping support for python2. Hoping that it was a PPA issue, I uninstalled the PPA and followed their manual installation instructions.

# update pip
python -m pip install --upgrade --user pip setuptools virtualenv
. ./kivy_venv/bin/activate
python -m pip install kivy kivy_examples

Launching again gave me errors like:

I solved this by installing pygame and pillow.

pip install pillow pygame

After that, I could successfully launch the UI.

Hmmm tricky, sorry for the trouble, but nice solution.

How do you think we can best make sure anyone else who has the same issue knows where to find this information? Maybe a link to this issue in the wiki page?

I think Google will pick this up, which feels fine. I just wanted it written down somewhere. :)

Sounds good. I'm going to close the issue in that case, it will be searchable but not on the todo list.
